Studying lower species is, at least, less fraught with political touchiness.

Their job was to study newly discovered alien species and determine how much of a threat they might prove to the Empire.

"These findings suggest that mink may provide an important model to study species barrier effects," Marsh observed.

The best studied species under this genus is the Citrus psorosis virus.

This can be a troubling idea, particularly to a biologist who studies species.

Much of their recent work has focused on primate genomes, although they have studied various other species as well.

They are required reading for anyone who studies species and speciation.

In studying invasive species, scientists often see a direct effect.

A little studied species, not much is known of its ecology or conservation biology.

The researchers say they will continue studying Australian species to see if other birds may have evolved this imposter-detecting ability.
